To all whom it may concern:

Be it known that I, EDWARD JOHNSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metallic lrVindow- Sashes, of which the following is a specification.

My invention relates to metallic window sash constructions of the general character disclosed in my co-pending application No. 474,988, filed January 29, 1909, and of which this application is a division.

The object of my invention is to rovide a'window sash so constructed that t e window lass can be readily inserted and removed from the sash from the inside thereof, and without damage to the glass or injury to the sash.

A further object is to provide a sash which shall be simplejn construction and cheap to manufacture, and which shall consist of but two parts, i. e., the main bod of the frame and an inside removable strip slidably detachable from the frame and adapted to be held in position in the frame by resilient fastening means, whereby a tight and elastic joint is secured.

A preferred embodiment of my invention is described in the following specification and illustrated in the accompanying drawings, in whichigure 1 is an inside elevation of the sash frame and the glass positionedtherein. Fig. 2 is a vertical cross-section on the line 22 of Fig, 1, and, Fig. 3 is a detail sectional view of part of the body and removable strip showin the manner of striking up the retaining ps.

-In the drawings, A indicates the main body of the frame which is formed of four sections of angular tubing joined in any suitable way at the corners, Fig. 1.' The outer edge of this frame is folded as shown in Fig. 2 and forms a rojecting flan e B, inclined upwardly an inwardly to orm an acute angle C with the upper face E. The inside corner D of the frame is pierced at intervals along the inner face E, as shown in Fig. 3, to form a li F. These lips are struck up from the face E to form an acute angle therewith. These lips are spaced at'fintervals along the edge, D of the frame; the number-depending upon the as shown in.

size of the frame and of the glass to be held therein, it being only necessary that the li s be located near enough together to'hold the glass firmly in position.

Supported upon the face E of each side of the frame, and adapted to be held in position thereon by the li F and the flange B, are the four glass-holding str ips G, as shown in Fig. 2. These strips are preferably composed of sheet-metal folded at or near its center to form a channel G adapted to receive and hold the edge of a glass plate. The lower edges of the faces G and G of this strip are adapted to be supported upon the face E of the frame. The face G is inclined to fit in the angle C formed by the outside flange B and the face E of the frame,

while the outer edge G is inclined in the opposite direction to fit into the angle formed by the face E and the lips F, as shown in Figs. 2 and 3. It will be apparent that the strip G may be inserted into operative position relative to the frame A either by bending the faces (l and G toward each other so that they may be slipped under the flange B and the lip F, or the strip may be slid longitudinally into its operative position from one end of the frame before the side pieces of'the frame are assembled.

This construction provides a sash which is easy to manufacture and which is made entirely from sheet metal, and which can be readily and quickly put together. The lip F and the flange'li securely hold the glass holding strip in position and produce between the frame and the strip a weathertight joint.

It will be obvious that minor mechanical variations may be made in this construction without departing from the spirit of the invention or sacrificing any of the material advantages thereof.

What I claim is:

1. A metallic sash consisting of a rectangular main body, said body being folded at one corner to form a flange projecting at an acute angle from the inner face of said body and a series of lips struck up from said inner face of said body adjacent the inside edge thereof and inclined at an acute angle with said face, and a glass-holding strip folded to form a centrally disposed longitudinal channel to receive and hold the edge of a glass, the edges of said strip being adapted for insertion in the angle of the outside flange and the angle under said lips, respectivelg, said sash consistin only of said main b o y and said lass-holding strips as described.

2. metallic sash consistin of a rectangular tubular body folded to orm a flange on the outside edge of its inner face, said flange forming an acute angle withqsaid'inner face, a series .ofllips onthe inside ed e of said inner face forming an acute an% e therewith and disposed in a line paral e1 with said flange, and a having a central longitudinal channel adapted to receive and hold a window glass, one edge of said strip being inserted under said lips whereby said strip is removably secured on the inner face of said body as described.

3. A metallic sash consistin of a main body, a longitudinal flange on t e outer part of its inner face forming an acute angle therewith, a series of lips struck up from the inner part of said face and inclined toward said flange, and a glass-holding strip detachably inserted in the angles formed by glass-holding strip said -,flan e and lilps with the face, said strip having a ongitu mal central channel adapted to receive and hold a glass, said face consisting of only the body part and the strip as described.

4. A metallic window sash consisting of a body partiianged on the outer edge of its inner ace and aving a series of lips on the inner edge of said face, said flange and said lips forming acute angles with said face and being thereby adapted for the insertion therein o a glass holdin strip; and an elastic glass holding strip olded to form a longitudinal central channel adapted to hold a window glass, and the edges of said strip adapted to be inserted in and removed from the angles formed by said face, flange and lips by transverse pressure applied to said strip as described, said sash consisting onl of said body part and said stri as describe EDWARD OHNSON.
